To all whom it may concern:

Be it known that I, WILLIAM S. PATTER- SON, a citizen of the UnitedStates, residing at Salt Lake City, in the county of Salt Lake and Stateof Utah, have invented new and useful Improvements in Lubricators, ofwhich the following is a specification.

My invention has relation to 'lubricators in which the oil is fedautomatically and which depends more or less upon the jarring of thelubricator by the movement of the machinery with which it is connectedto feed the oil.

The feeding device is adjustable from the outside and means are providedto indicate the quantity of oil in the cup at all times.

Simplicity has been an important object in working out this invention,and by it I am able to cast or mold in one piece the oil-cup, its topand bottom, the neck, the base, and a lateral housing for the adjustingdevice.

This fact minimizes the cost of manufacture and insures a very strongand compact structure.

The accompanying drawings illustrate the device, its various featuresbeing referred to by letters, similar letters denoting correspondingparts in the several views.

Figure 1 is a plan view of the top of the device with the oil-inletclosed. Fig. 2 is a similar view with the oil-inlet open. Fig. 3 is aside elevation of the invention Fig. 4 is a partially-vertical sectionon the line :20 9c of Fig. 1, the lubricator being mounted on a journal,which is shown fragmentarily. Fig. 5 is an elevation of an eyebolt, andFig. 6 is a plan of the feeding-lever and a cross-section of the lugs.

The letter A designates the oil cup or reservoir. It is approximatelysquare and is cast integrally with the neck 0, base E, lugs K, andhousing I.

a is the oil-inlet opening into the cup A through the top a. This inletis closed by a plate B, swinging on a pivot screw-bolt and nut b, whichextends down through the top A spring b on this bolt 6 bears against theunder side of the top a and the head I) on the bolt. By these means theplate B is held in close contact with the top of the cup A. A nib b onthe under side of the plate B engages a socket a in the top a, wherebythe plate is normally held in place' An oil-channel 0 extends downwardfrom the cup A into the neck 0, having its lower end enlarged to form achamber a, which opens downward through the base E.

L is aball-valveloosely seated in the chamber c and adapted when pressedupward to close the lower opening of the channel 0.

G is a lever loosely fulcrumed on a shaft g, which has bearings in thelugs K on the lower side of the base E. This lever G supports the ball Fand moves it vertically to open and close the channel a. The lever G isprovided with a finger g at a point opposite to its fulcrum, which isengaged by a loop h on the lower end of a spring H. The upper end ofthis sprin is attached to an adjusting-bolt 71. The middIe portion h ofthis bolt is angular and the bolt is longitudinally movable in theangular opening a through the housing I. The upper end of this bolt isround and threaded to engage a nut J, having a wrenchseat on its top andradial notches 7' on its lower face. These notches are engaged by teeth'i on the upper surface of the housing I. L L are screw-eyeboltsengaging from beneath holes 6 through the base E and extending into anoil-box M above the shaft or bearing N to be lubricated. The eyes of thebolts L are engaged by short bolts 0, which extend through the sidesof'the oil-box. The small channels m and n conduct the oil from the boxto the surface of the shaft N.

Theball F and the lever G are easily removed by unscrewing the nut J onthe bolt h. Then by drawing down the spring II its loop is readilydetached from the lever G and the ball drops out.

The oil-gage comprises a float P in the oilcup carrying a vertical wirep, which extends upward through a hole p in the top of the cup A. Themiddle part of the wire p is bent laterally and then downward outside ofthe cup and is terminated at a point in the same horizontal plane as thefloat P.

This lubricator is operated as follows: Move the plate B to one side andsupply the cup A with oil. Adjust the lever G by means of the nut J onthe rod h, so that the jarring to which the device will be subjectedwill give the lever G a very slight vertical movement. This movementraises and lowers the ball F, which opens and closes the oil-channel cand allows a limited downflow of the oil around the valve F and thelever G and on down to the part to be lubricated. If too much or toolittle oil is emitted, the nut J is turned to correct the difficulty andto secure the exact quantity required. The indicator announces at alltimes the quantity of oil in the cup A.

Having now described the invention and the manner of using it, what Iclaim, and desire to secure, is'

1. A lubricator whose oil-cup, neck, base, adjuster-housing and lugs onthe lower side of said base are integral, an adjustable lever journaledin said lugs, an intake for the oil and an adjustable cover therefor asdescribed.

2. A lubricator comprising an oil-cup, provided with an oil-inlet in itstop, an oil-channel extending downward from said cup and opening into achamber, a ball-valve in said chamber to close said channel, and anadjustable lever to support and vertically move said ball for thepurpose specified.

3. A lubricator comprising an oil-cup pro- In testimony whereof I affixmy signature I in presence of two subscribing witnesses.
